Policy-Driven Infrastructure: Separating User Intent from Configuration Procedures

Listen to the Podcast

January 28th, 2015

policy_driven_infrastructure_mike_sandeepThe focus on separating user intent from infrastructure is an important new insight into how cloud environments should be run.  To drive forward this approach, Group-Based Policy is currently being developed for both OpenStack and OpenDaylight open source projects. Mike Cohen, Director of Product Management and Sandeep Agrawal Senior Marketing Manager, both of whom work at Cisco Systems join me to talk about Group-Based Policy or using intent to manage infrastructure.

CiscoProgrammingEnvironmentNexus9000BradleyWongToday’s networks are restricted to configuration programming via CLI, but what if applications can call upon network resources automatically or if application developers are provided access to network state, topology, performance and other information? How might applications change and user experience improve? How may a networking programmable environment enable automated provisioning, orchestration and management? Could a programmable network enable a new era of IT and an industry of network aware applications just when the Internet of Things is starting to emerge? The Cisco Nexus® 9000 product line provides a wide range of programming options through an enhanced version of the Nexus Operating System (or NX-OS) that ranges from APIs to direct programming via its built-in Linux BASH environment, RPC, RESTful APIs, JSON, Python etc. I’m joined by Bradley Wong, Distinguished Engineer, Technical Marketing at Cisco, as we review the Cisco Nexus programming environment, its programming options provided to developers, use cases and potential industry impact.

Nexus9000ProgrammingEnvironmentDemonstratedLillianQuanTo understand the depth of the Cisco Nexus® 9000 programming environment, Lillian Quan, Technical Marketing Engineer at Cisco, demonstrates the richness of this new platform. We start with standard CLI comments then move to the Nexus API environment that generates JSON or XMP code. We then utilize this code to demonstrate automation of repetitive network engineering task via Splunk and real-time graphic of network data via Graphite to create a NOC dashboard. After watching this video, network engineers will want to enroll in a Linux course while DevOps will finally be able to use familiar tools to access network data and information.

November 6th, 2013

CiscoNexus9508LatencyTestResultBradleyWongWhile most companies announce products long before first customer ship with long road maps of when product features are available, Cisco’s Nexus® 9508 is ready now. The independent and open industry Lippis/Ixia team test the Nexus® 9508 at 288-40GbE capacity for layer 3 unicast plus IP multicast latency and congestion management via RFC 2544, 3918 and 2889, respectively. This test is a new industry record as no other data center switch has been tested at 288 40GbE ports. What are really impressive are the results and the engineering achievement of the Cisco team. I’m joined with Bradley Wong, Distinguished Engineer, Technical Marketing, at Cisco, as we review the Cisco Nexus® 9508 test methodologies and results.

By Bob Laliberte, Senior Analyst, Enterprise Strategy Group

As organizations continue to virtualize their environments and build out cloud environments, the requirement for more flexible and agile networks is becoming a priority. One of the more promising network architectures being developed to address these challenges is software-defined networking (SDN). Although this space is still being defined, one aspect of SDN, network virtualization, is gaining mindshare. This technology leverages a virtual switch, controller, and virtualization technology. IBM has just announced its offering in this area, called Software Defined Network for Virtual Environments or SDN VE.

As 10 and 40GbE data center networks provide very low latency with less than 10ns of jitter and favorable price points, the ability to converge storage and user traffic onto one physical network has become realistic. In this white paper, Arista details various cloud provider storage options and how they can gain from transporting block storage flows over a 10GbE network.

Arista EOS offers multiple programmable interfaces for applications. These interfaces can be leveraged by applications running on the switch, or external to EOS. Arista’s newest interface, EOS API (eAPI), allows applications and scripts to have complete programmatic control over EOS, with a stable and easy to use syntax. Once the API is enabled, the switch accepts commands using Arista’s CLI syntax, and responds with machine-readable output and errors serialized in JSON, served over HTTP. DevOps teams will be very impressed.

Arista Networks’ award-winning Arista 7500 Series was introduced in April 2010 as a revolutionary switching platform, which maximized data center performance, efficiency and overall network reliability. It raised the bar for switching performance being five times faster, one-tenth the power draw and one-half the footprint compared to other modular data center switches. Just three years later, the introduction of the Arista 7500E Series modules and fabric delivers a three-fold increase in density and performance with no sacrifices on functionality, table sizes or buffering with industry-leading 1,152 x 10GbE, 288 x 40GbE or 96 x 100GbE in the same quarter-rack 11RU chassis. This whitepaper details scale-out cloud network designs enabled with the new Arista 7500E second-generation linecard and fabric modules.

Cisco Enhances VXLAN: Eliminates IP Multicast Requirement, integrates virtual services via vPath plus connects to legacy networks

Listen to the Podcast

May 27th, 2013

Han_Yang_Cisco_Enhances_VXLAN_Eliminates_IP_Multicast_Requirement_integrates_virtual_services_via_vPath_plus_connects_to_legacy_networksCisco introduced enhancements to its VXLAN implementation in the Nexus 1000V virtual switch that overcomes the requirement for IP Multicast. In addition Cisco is integrating vPath to VXLAN for service insertion that stitches virtual services into VXLAN overlay tunnels. Network services might include virtual firewalls, application delivery controllers, WAN optimization, network monitors, etc. A final VXLAN challenge that network teams are facing is how to integrate VXLAN into legacy networks and with existing physical networks, appliances and the enterprise WAN. We’ll hear if Cisco has any solutions to get around this issue as well. Han Yang of Cisco joins me to discuss VXLAN, without multicast and with vPath, and how it can be used to deploy virtual network overlays.
